Wastewater Network Modelling Project - Gauging Quality Assurance

⁠⁠⁠New Plymouth District Council is embarking on a programme to develop detailed knowledge of the existing district-wide wastewater network and to use this information for the ongoing strategic management of the system.

The Wastewater Network Modelling Project is the first stage of the programme which is the development of calibrated Infoworks ICM wastewater computer models of the entire network. The project includes the development of several guideline documents for process standardisation, asset data survey, gauging and an Inflow and Infiltration investigation programme.

The Wastewater Network Modelling Project has three related Peer Review and Quality Assurance processes:

• Wastewater Modelling Peer Review
• Survey Quality Assurance
• Gauging Quality Assurance

This Request for Tender is for the Gauging Quality Assurance component of the project.

It is anticipated that the Gauging Quality Assurance Consultant (hereafter referred to as the Respondent) will be engaged around the same time as the Wastewater Network Modelling Consultant. The aim is that the Quality Assurance Consultant is a member of the overall project team and will contribute to the successful progress of the project. It is the intention that the Quality Assurance Consultant will be resolving issues as the project progresses rather than being separate from day-to-day operations and having a more 'policing' type of role.

The Gauging Quality Assurance role is a highly technical and skilled senior specialist position. The role could be filled by an individual or small team from within a larger consultancy or from a sole practioner consultancy. The aim of this procurement is to engage the best individual or small team for the Quality Assurance role.

The overall scope of the Wastewater Network Modelling Project Gauging Quality Assurance Review is to:

• Undertake a Quality Assurance Review of the Wastewater Gauging Programme component of the Wastewater Network Modelling Project
• Undertake Field Audit gauging review
• Undertake Office Audit gauging review
• Sign off all Survey Quality Assurance Review aspects
